The bodies of four people, including two children, were found in the home in the 13000 block of Saratoga Springs Place, off Old Heady Road.

The coroner identified the family as Brad and Billie Jo Hettinger and their children, Collin, 5, and Courtney, 4.

The coroner said Brad Hettinger, 33, died of a single gunshot wound to the head.

Billie Jo Hettinger, 32, died of a gunshot wound to the chest and head, but also suffered thermal injuries in the fire.

The children died of gunshot wounds to the head and had thermal injuries from the fire.

An in-home alarm system alerted authorities that there was a fire in the home.

Investigators said firefighters did not know of the shootings until they found the bodies. The coroner said the children were found in their beds, Billie Jo Hettinger was found in the basement and Brad Hettinger was found on the first floor of the home.

According to a priest at Saint Michael's Catholic Church, the four people were members of the church.

Louisville homicide detectives and arson investigators are working to piece together what happened.

Fire crews said it is one of the most devastating fires they have ever had to work because of the victims involved.

The LMPD did not comment Monday on the motive for the murder-suicide.

“This is a safe place for kids to be, and a nice place to raise a family. For something to happen this close to home, it's really hard for our community,” said Eddie Smith, one of the family's neighbors.

He said even late Sunday morning, nothing seemed strange.

"My wife walked the dog, saw them, waved to her just like a normal day,” Smith said.
